As shown by select quotes from Linnaeus, John Edward Gray and Otto Furhmann, biologists have long complained about the dearth of our knowledge on caecilians (Linnaeus said that amphibian experts know very little, and what they do know is wrong).

Gray [John Edward Gray (1800-1875) appointed Keeper of the Zoological Collections in the British Museum in 1840.) were but an intelligent activity instead of being a sort of zoological whirlwind, what a deal he might do.
